Hi Ron,
How about LP2950-N/LP2951-N, it has a "Output Programmable From 1.24 V to 29 V", the typical dropout voltage is 380mV @100mA, so I guess you may get a 1.0V output voltage with 1.5V Vin. Below is the Dropout Curve just FYR.
Another possible…
Part Number: LP2951 Hello,
are you able to clarify what the ">" in the marking callout would mean? Is this a variable callout of the last digit that can be anything less than D?

This is buried in the LP2951-N datasheet on Page 6, Note 3:
(3) All LP2950 devices have the nominal output voltage coded as the last two digits of the part number. In the LP2951 products, the 3-V
and 3.3-V versions are designated by the last two digits…
Other Parts Discussed in Thread: LM317 , LM337 , LP2950 , LM337-N I have used the LM317 and LM337 regulators many times in this configuration. In this case the LM337 output is set to 9V. Superimposed is a sawtooth with 180mV amplitude. The frequency and…
Part Number: ADC104S021 Other Parts Discussed in Thread: ADC128S102 Tool/software: I am asking question on what the recommended cable capacitance on SPI interface to this component is. This component is connected via 3m cable and what is maximum allowed…
Hello,
The UCC3806 is a dual output controller though it can be used in a flyback where only one of the outputs are used to drive the switch it might be better to choose a single output controller. Look at page 46 of the attached under General Purpose…
Siyu,
I think the toggle flip-flop in the block diagram on page one of the spec should have let you know that the max you will get with this device is 50% duty.
Go to page 43 and 44 of the attached and select a more suitable part.
Peter,
i am enclosing the Power Management Guide for 2011. The section you will be interested in starts on page 43 and actual devices listed on page 46, With the minimum information you have given me I would expect that you will want something like…
